Specification of Letters Patent.

Patented Apr. 25, 1911.

Application filed September 9, 1909. Serial No. 516,861.

T 0 all whom it may concern:

Be it known that I, MERVIN DANIEL Lower, a citizen of the United Statesof America, residing at F erron, in the county of Emery and State ofUtah, have invented certain new and useful Improvements inSpringJVheels, of which the following is a specification, referencebeing had therein to the accompanying drawing.

lily invention relates to improvements in spring wheels, and has for itsobject to provide a spring wheel, which will readily yield to thesurface of the road as well as to all inequalities and obstructionsencountered, the compression and jarring to which it is subjected beingabsorbed and compensated for by other portions of the wheel.

Other objects and advantages of my invention will appear in the courseof the following specification.

In the accompanying drawings :Figure 1 is a side elevation of thepreferred form of my wheel. Fig. 2 is a section on the line a"00 of Fig.1, looking in the direction of the arrow. Fig. 3 is a side elevation ofa modified form of my wheel. Fig. 4e is a section on the line p z ofFig. 3, looking in the direction of the arrow.

Referring to Figs. 1 and 2 of the drawings, which illustrate thepreferred embodiment of my invention, 1 designates the rim of a wheel,which is preferably made of resilient metal. To the inside and centrallyof the rim at equi-distant intervals are suitably secured short spokes,alternately designated 2 and 3, the tops or free ends of which arebifurcated, as at 2 and 3 respectively. In each bifurcation 2 arepivoted the vertically arranged reduced ends 1* and 5 of a pair ofoppositely disposed diagonal arms or rods 4 and 5, which are bothlaterally inclined in the same direction. In each bifurcation 3 arepivoted the reduced vertical ends 6 and 7 of a pair of oppositelyarranged diagonal arms or rods 6 and 7, which are both inclinedlaterally in the same direction, but in a direction opposite to that ofthe rods 4 and 5, as best shown in Fig. 2.

Each of the arms 4 and 5 is provided with a reduced vertically arrangedinner end 4: and 5 respectively, and are pivoted in pairs, that is, theend 4 of each rod 4 is pivoted to the end 5 of the opposite rod 5, bysuitable means in bifurcations formed in the vertically arranged ends 8of arms or rods 8. The arms 8 are laterally extended, but at their innerends are provided with vertically extended portions 8 havingbifurcations into which projects a flange 9 to which they are pivoted.Flange 9 is secured in a circumferential groove 10 formed near the endof a hub 11.

Each of the arms 6 and 7 is provided with a reduced vertically-arrangedinner end portion 6 and 7", respectively, and are pivotally secured inpairs, that is, the end 6" of each arm 6 is pivoted to the end 7 of theopposite arm 7, by suitable means in a bifurcation formed in thevertically-arranged end 12 of an arm 12. The arms 12 are laterallyextended and oppositely inclined to the arms 8 and are provided at theirinner ends with a vertical portion 12 provided with a bifurcation intowhich proj ects a portion of a. circumferential flange 13 secured in acircumferential groove 14: formed near the other end, or end opposite tothat carrying the flange 9, of the hub 11.

Referring now to Figs. 3 and 4 of the drawings, which illustrate amodified form of my wheel, 15 designates the rim which is preferablyformed of resilient metal, the same as the rim shown in Figs. 1 and 2.Suitably secured at equi-distant points centrally of the inside of therim 15 are short spokes 16. The spokes are bifurcated, as at 1.6 attheir inner or free ends, and in each bifurcation is pivoted the reducedends 17 a and 18 of a pair of oppositely disposed diagonal arms or rods17 and 18. The inner ends of the diagonal arms 17 and 18 are re duced asat 17 and 18", and are pivoted in pairs, that is, the end 17 b of thearm 17 and the end 18 of the arm 18 are pivoted, by suitable means, inbifurcations 19 formed in the ends of yokes 20. The yokes 20 compriseoppositely divergent or laterally disposed arms 21 and 22, the innerends 21 and 22 respectively, of which are vertically arranged andsuitably bifurcated, as shown. Into the bifurcations of the ends 21 ofthe arms 21 projects a flange 23 and into the bifurcations of the ends22" of arms 22 projects a flange 24. Flange 23 is secured in a suitablecircumferential groove 25 formed near the end of hub 26, and flange 21is suitably secured in a circumferential groove 27 formed near the otherend of the hub.

It will be noted in Figs. 1 and 2, that the vertical reduced endportions 1 5 4 5 6, 7 6 and 7 are suitably rounded at their ends, andare so pivoted in the bifurcations, hereinbefore referred to, as toallow for their free movement. So also with Figs. 3 and t, the reducedend portions 17 18 17 and 18 have their ends rounded and are so pivotedin the bifurcations as to admit of their free movement.

What I claim is 1. In a spring wheel provided with a flanged hub, spokesprovided with bifurcati ons, divergently arranged laterally inclinedarms provided with vertical end portions, said vertical end portions ofsaid divergently-arranged arms being pivotally mounted in thebifurcations of said spokes, and laterally inclined arms provided withvertical portions, the vertical portions of said laterally inclined armshaving bifurca tions, the vertical end portions of saiddivergently-arranged laterally inclined arms and the flanges of the hubof said wheel being pivotally mounted in the bifurcations of thevertical portions of said laterally inclined arms.

2. A spring wheel comprising a flanged hub, bifurcated spokes carried bythe rim of said Wheel, toggles pivotally mounted within the bifurcatedends of said spokes, laterally inclined arms provided with vertical endportions, said vertical ends being provided with bifurcated ends, eachof said arms having a pair of toggles pivotally mounted in itsbifurcated outer end and the bifurcated inner end being pivotallyconnected to said flanged hub.

In testimony whereof I hereunto aflix my signature in presence of twowitnesses.
